To whom itmay concern,-l v.

Be it known that we, MARTIJ L. .Museen and Conexionr llW. Grnsosgof Grand '.Blanc, in the county of Genesee and' State Vof Michigan, have invented a new and useful Improvement in Machines for Upsetting Iron; and weldo declare thatthe following is a true and accurate description thereof, reference heilig had to the accompanying drawing and to' theletters lof' reference marked thereon rand being a part of this specification.

Figure l is a-perspective view of our machine.

Figure 2 is a vertical sectional view of the adjusta-- blel slides on the line a; win 1.

4 x Figure 3 is a plangview of thebottom of the rigid and movable bed-plates.

Figure 4t is' a view of the operating-lever, 4showing the method of connecting the same.

VLike letters indicate like parts lin eachfigurc.

Themature of this invention Vrelates'to an limproved construction of thatV class of machines employed for upsettingiron, and consists ina n'ovel method of connecting and extending lthe operatinglevcr, and in a new and `peculiar arrangement and adaptation offits variousvparts to perform the desired work.

lIn'the drawing- 'A represents the' topfot' a block or bench upon which the apparatus operates.

B is abcd-plate secured to the bench by means of..4

bolts a., and may have projections orlugs cast upon its under. side, whichrnay engage with correspondiiig 4recesses in the top of the bench.

,(l is a sliding bed-plate resting and operating upon the bench, but not secured thereto.

f A rod, b, passes longitudinally through both these .bed-plates, and is secured tn the outer end of C by The opposite end of this rod is pivoted to thecaxn D in such a manner that the partial rotation of the lcani by means ofthe lever E will compel the bedplate C teadvnce and recede toward andfrom two rigid bed-plate, B.

A plate, (l, is secured upon the bench in such a man- -ner that the cam inipinges against it when it is desired to compel the bed-plate C to recede from B; reversing the motion, the cam ilnpingcs against the end ofbcd-plate l5, and causes the bed-plate O to advance toward B, Thy this means shortening or shrinking the iron when the latter is confined and 'held in position, as hereinafter described.

The under side ot the lever E is provided with a projection or lug, t, at the end where said lever is oonnccted to the extension o1` prolongation of ,the same.

` .The strap h, to which is securedthe prolongation F-,is pivoted to the lever E, and is provided upon its upper face, at the point of junction, with a series ot' .recesses,i, corresponding .in size with the hereinbe. 'fore-mentioned lng upon the under side of the end of the lever E; and, by means of the engagement oi' said lug or projection with the recesses ,auy change in the shape of the combined lever may be made to suit the space in which the saine is operated, thereby enabling the apparatus yto be used in a corner or in a small compass.

.'lhe two' bed-plates vare provided with projections G, whose top faces are serrated. Upon these projections rest the adjustable slides H, whose bottom faces" arerserrated, andengage with the serrations upon4 the Vtop faces 'of the projectiens.

Bolts 7;, secured to projections G, pass upward through the slots l, and, by means of suitable nuts, allow the slides H to be held rigidly in their engagemeut, as hereinbefore recited, and also of being adjusted to suit the widthjof the iron to be operated upon.

Dovctailed into the inner ends of these slides H arethe serrated stud-plates m, to assist in grasping and holding the iron to be shortened or shrunk.

The two bed-plates 'are'also provided upon their -opposite sides with other projections, K, to which are pivoted the levers L. To the ends of these levers are secured, by knuckle orother joints, u, the plates M,

in the4 inner .facesof which are dovetailed serrated` steel'plates N, which are designed, with the `serrated .plates m, te hold lthe iron being operated upon.

ATheadjustability of the plates M upon the levers L, by means o the joints 41., allows of their grasping and holding various shapes of iron against the plates tn, whilethe adjustability of the slides II,'as de scribed, allows anydesired width of iron to be operated upon.

What we claim as 'our invention, and desire to seeure hy Letters Patent, is

1. In iron-upsetting machines,the combination of the levers E and F, when connected and operating substantially. as herein set forth.

2. The arrangement of the bed-plates B and G, cani D, levers E, 19, and L, slides H, plates M, bolts a, rod b, plate d, bolts k, steel plates m N, and joints fn., ,when combined and operating substantially -asand for the purposes shown and described:
